He is a former senior Justice Department official who continued to serve as a white-collar defense lawyer. That word came one day before the Federal Bureau of Investigation director that Trump fired last month, James Comey, was to testify in public on Capitol Hill for the first time since that dismissal.
Wray rose to head the department's criminal division in the Bush administration and oversaw investigations into corporate fraud, at a time when Comey was deputy attorney general.
"He served on the president's Corporate Fraud Task Force and oversaw the Enron Task Force and other major fraud investigations, both around the country and internationally", Wray's biography at King & Spalding states. As described by US today, then-deputy attorney general Comey was upset over the White House's effort to persuade AG John Ashcroft to reauthorize a warrantless surveillance program from his hotel room.
Wray, in the same statement issued by the White House, said he was honored to be selected. With a strong law enforcement background, Wray is a traditional choice for the job. Trump had entertained current and former politicians for the role. Joe Lieberman, D-Conn. Though favored by Trump, Lieberman would have faced a challenging confirmation process; he pulled his name from consideration. Trump said he knows Wray will "again serve his country as a fierce guardian of the law and model of integrity" if confirmed by the Senate.
On Twitter, he only offered that Wray is "a man of impeccable credentials".
A GOP colleague was more cautious. James Lankford, a member of the Senate Intelligence committee. Oklahoma Sen. James Lankford said in a statement that "we will evaluate Christopher Wray's qualifications" in the coming weeks.
In May, Yates testified in front of a Senate judiciary subcommittee regarding the Trump campaign's alleged ties to Russian Federation, particularly former Trump national security adviser Michael Flynn's contact with Russia's Ambassador to the US Sergey Kislyak.
Mr Comey is expected to describe his encounters with Mr Trump in the weeks before his May 9 firing.
Christopher Wray, a Yale Law school graduate, is now a partner at an worldwide law firm, King & Spalding. He represented Christie in the case in which two of the governor's aides were convicted of plotting to shut down bridge lanes to spite a Democratic mayor who wouldn't endorse Christie. During tense times, Christie said he would make one call: to Wray.
Trump fired Yates, who was serving as acting attorney general, shortly after he took office for refusing to enforce the travel ban.
Wray had been Christie's personal attorney during the investigation over the 2013 "Bridgegate" scandal - which led to charges against several close Christie allies, but never against Christie himself.
